TaxonomyChaetodon lunula belongs to the large subgenus Rabdophorus which might warrant recognition as a distinct genus. In this group, its closest relative is probably the very similar Red Sea raccoon butterflyfish or diagonal butterflyfish, C. fasciatus. Other close relatives appear to be the black butterflyfish, C. flavirostris), Philippine butterflyfish, C. adiergastos, and perhaps also the unusual redtail butterflyfish, C. collare. Although the coloration of this group varies greatly, they are all largish butterflyfishes with an oval outline, and most have a pattern of ascending oblique stripes on the flanks. Except in the red-tailed butterflyfish, there is at least a vestigial form of the "raccoon" mask, with a white space between the dark crown and eye areas.[4][5] DescriptionBiologyChaetodon lunula is a nocturnal species that usually lives in small groups. Adults feed mainly on nudibranchs and small invertebrates, but also on algae and coral polyps.[2]DistributionThis species can be found widely throughout the tropical Indo-Pacific region (East Africa to the Hawaiian and Marquesan islands, north to southern Japan) and in the southeast Atlantic (South Africa). It is missing in the Red Sea.[2] HabitatThis species prefers seaward reefs and shallow reef flats of lagoon, at a depth of over 30 m.[2] In the aquariumThe raccoon butterflyfish is generally not aggressive towards other fish, with the exception of lionfish and triggerfish. In captivity, the typical lifespan of a raccoon butterflyfish is five to seven years. It has been observed as a beneficial predator of Aiptasia and Majano sea anemones. They will eliminate this nuisance pest within a two- to six-week period depending on the anemone population and size of the tank; however, they will eagerly feed on any soft corals and may cause more harm than good to the decoration. In a confined environment, this species is prone to succumbing to "marine ich", infection by the ciliate Cryptocaryon irritans. References1. ^{{aut|Pyle, R., et al.}} 2010. Chaetodon lunula.
